All muzzle brakes are not created equal

This is what happens to merchants that team up with people who are cheapskates! Over the last few years we have told them that a pressed-on hider will fail. The image below was taken from the M14 Firing Line Public Forum.

We make our muzzle brakes:

  • from 8620 and 4140 steel
  • heat treat it
  • thread and SCREW it together
  • install a set screw in the bottom to engage the threads for saftey
  • Loctite&ref; it
  • and then stake it
